The Wacker Neuson Fuel Line is a genuine OEM component designed for the HI series indirect-fired air heaters, including the HI 120HD, HI 200HD D, HI 300HD D, and HI 400HD D. Sourced directly from Wacker Neuson, this fuel line is manufactured to the exact specifications required for safe, dependable fuel delivery in diesel-powered heating applications. It is a direct-fit replacement for the models listed, requiring no improvised adapting or modification to the fuel system. Keep a verified OEM part on hand to maintain uninterrupted heat output on cold-weather jobsites.
Key Features
- OEM-Grade Fuel Compatibility — Manufactured from materials rated for continuous diesel fuel contact, maintaining integrity under the pressure and temperature cycles of indirect-fired heater operation.
- Direct-Fit Replacement — Engineered to the original routing and connector dimensions, so the line seats correctly within the HI series fuel system without reworking surrounding components.
- Broad HI Series Coverage — Confirmed fitment across the HI 120HD, HI 200HD D, HI 300HD D, and HI 400HD D diesel indirect air heaters.
- Consistent Fuel Delivery — A sound fuel line maintains steady flow to the burner assembly, supporting stable flame output and consistent heat performance across the unit's rated capacity.
- Fuel System Safety — A cracked or degraded fuel line creates leak risk in a combustion environment. Replacing with a genuine OEM part restores the integrity of the fuel circuit and keeps the heater operating within its designed safety envelope.
The fuel line carries diesel from the tank to the burner assembly inside an indirect-fired air heater. It must maintain a continuous, leak-free seal under the vibration, heat cycles, and fuel pressure present during heater operation. When the line cracks, kinks, or deteriorates, fuel flow becomes restricted or inconsistent, leading to burner ignition failures, uneven heat output, or fuel leaks that pose a direct safety risk in an enclosed or temporary heating environment. Replacing a worn line with the correct OEM part — Wacker Neuson 5000183934 — restores proper fuel circuit function and keeps the heater running at its rated output.
